    Description / Table of Contents: On Polygermanes. VI. 1,4-Diiodooctaphenyltetragermane I-(Ph2Ge-)4I, Crystal Structure and Vibrational SpectraThe crystal structure of the title compound has been determined and refined to a R of 0.060. The arrangement of the heavy atoms in the six membered chain I-Ge4-I is all trans with a fully staggered conformation of the substituents. The torsion of the phenyl rings results in a molecular propeller with eight wings (symmetry Ci). Distances: Ge - Ge 245.1 (1) and 245.9 (2), Ge - I 255.9 (1) pm. The packing of the I-(Ph2Ge-)4I molecules resembles a tetragonal body centred sphere packing with coordination number (10+4).Domains for the 12 normal vibrations of the chain I-Ge4-I are given.
    Notes: Die Kristallstruktur der Titelverbindung wurde bestimmt und bis R = 0,060 verfeinert. Die 6gliedrige Schweratomkette I-Ge4-I ist all-trans angeordnet mit durchgehen d gestaffelter Konformation der Substituenten. Die Verdrillung der Phenylringe ergibt ein achtblättriges Propellermolekül (Ci-Symmetrie). Abstände: Ge - Ge 245,1 (1) und 245,9 (2), Ge - I 255,9(1) pm. Die I-(Ph2Ge-)4I-Molekeln packen nach Art einer tetragonal-innenzentrierten Kugelpackung mit (10+4)-Koordination.Bereiche für die 12 Normalschwingungen der I-Ge4-I-Kette werden angegeben.
